Facebook founder Mark Zuckerberg — who lashed out at Donald Trump's campaign vow to build a wall to keep out illegal immigrants — is under fire for constructing a scene-blocking, 6-foot wall around his sprawling Hawaiian estate.

"It’s really sad that somebody would come in, and buy a huge piece of land and the first thing they do is cut off this view that’s been available and [appreciated] by the community here for years."

The stone wall is blocking the ocean view along much of his $20 million, 700-acre property, according to the newspaper.

It's a "monstrosity," resident Donna Mcmillen complains.

Shosana Chantara tells the newspaper that Zuckerberg could make everyone happy if he just took the wall down.

"It’s a beautiful island, and, by and large, people care for one another. That would include Mark," she tells the paper. "In the case of this wall, all he needs to do is take it down, so people have the view and the breeze back. It would end all discussion. That’s all we’re asking."
